What is HD and do you really need it for your next presentation? Get the straight scoop here.
HD stands for “high definition” and, as the name implies, refers to the image quality of television or video. HD TV is a type of television signal, broadcast in the 16:9 aspect ratio (as compared to NTSC’s 4:3 aspect ratio). HDTV resolutions are increased from 640 x 480 to either 1922 x 1080 (or 1080i) or 1280 x 720 (or 720p). Because the HDTV signal is digital (rather than analog), the signal can carry huge amounts of information, including full digital audio with multiple channels.
Many television viewers prefer HD because of its vivid, lifelike imagery; ultimate showcase of the finest details; and aspect ratio that mirrors traditional film.
Whether or not you need HD for your next speaking presentation depends on the nature of the material you’re presenting. The more detailed your presentation images, the more appealing (and necessary) HD becomes. Got complex graphics? Detailed imagery? Some examples of presentations requiring HD might include: photography training, video editing, detailed charts and graphs, statistical data, film and entertainment industry, high-profile presentations (where it pays to impress by going the extra mile), etc.
Your audience is another factor in determining whether or not you need HD technology. How large is your audience? How close will they be seated to the projection screen? What kind of lighting is available in the room? How familiar are the attendees with the material you’re presenting?
